About Image Compression

Large image files slow down email delivery, social media uploads, and website load times. This tool compresses JPG, PNG, and WebP images directly in your browser using the Canvas API. Adjust the quality slider to balance file size and visual quality — each file shows the original size, compressed size, and percentage reduction in real time. All processing happens locally; files are never sent to a server.

How to Use

  1. 1Drag and drop JPG, PNG, or WebP files (multiple files supported)
  2. 2Adjust compression quality with the slider (80 is a good starting point)
  3. 3Click "Start Compressing"
  4. 4Check the file size reduction and download your compressed files
